Hair loss is a common side effect of cancer treatment. This is a real concern for many cancer patients. The image of a cancer patient masking hair loss is all too familiar. Chemotherapy drugs usually aim to kill growing cancer cells.

For some people who have undergone cancer treatment, hair regrowth after chemotherapy is significant. Chemotherapy kills cancer cells, but it also kills healthy cells. That's why most people will lose at least some of their hair while undergoing chemotherapy.
